Following a successful commissioning and start-up, we believe that two grinding lines at Las Bambas, Perú, each consisting of one SAG Mill and one Ball Mill (this mill combination is uniquely specific to Las Bambas ore types), are operating at design throughput of close to 140,000 tpd and within the range predicted by DJB from a managed multi-sample geometallurgical testing program (i.e., no pilot plant tests).
Your Project, whether small or large-scale, preliminary or more advanced, could benefit from our multi-discipline approach. Please contact us with your requirements at ddbarratt@uniserve.com.
DEVELOPMENT OF SPECIFIC power consumption (kWh/t) FOR CRUSHING, PRIMARY & SECONDARY MILLING, AND TOTAL BY SAMPLE OR UGM.
DEVELOPMENT OF BALL WEAR RATES (g/kWh) FOR PRIMARY & SECONDARY MILLING, AND TOTAL BY SAMPLE OR UGM FROM BOND Ai MEASUREMENTS AND DJB’s IN-HOUSE EMPIRICAL EQUATIONS.
CALCULATION OF LINER, WEAR RATES (g/kWh) FOR CRUSHING, PRIMARY & SECONDARY MILLING, HPGR, AND TOTAL BY SAMPLE OR UGM FROM BOND Ai MEASUREMENTS AND DJB’s IN-HOUSE EMPIRICAL EQUATIONS.
